Setting the Time Program for DHW Heating
H The time program for DHW heating is made up of time
phases. One time phase from 5:30 to 22:00 h for every
day of the week is set at the factory.
H Automatic mode is set at the factory for DHW heating.
This means that, in standard heating mode, the DHW
is reheated to the set temperature. To ensure that hot
water is available at the start of standard heating mode,
the time phase for DHW heating begins automatically
half an hour earlier than the time phase for standard
heating mode.
H If you don’t want the automatic mode, you can select
up to 4 individual time phases per day for DHW heating,
which can be the same for every day of the week or
different. Set the start and end points for each time
phase.
H When setting, bear in mind that your heating system
requires some time to heat the DHW to the required

Maintenance
Vitotronic 300 GW5B, 300-K MW1B Operating
Maintenance
Cleaning
All equipment can be cleaned with a commercially
available domestic cleaning agent (non-scouring).
You can clean the front of the programming unit with
a microfibre cloth.
Inspection and maintenance
Regular maintenance ensures trouble free, energy
efficient, environmentally responsible and safe heating.
Your heating system must be serviced by an authorised
contractor at least every 2 years. For this, we advise you
to arrange an inspection and maintenance contract with
your local heating contractor.
Boiler
Increasing boiler contamination raises the flue gas
temperature and thereby increases energy losses.
For that reason, all boilers should be cleaned annually.
DHW tank (if installed)
Maintenance and cleaning should be carried out no later
than two years after commissioning and thereafter as
required.
Only a qualified heating contractor should clean the inside
of a DHW tank and the DHW connections.
Refill any water treatment equipment (e.g. a lock
or injection system) in good time, if such equipment
is installed in the cold water supply of the DHW tank.
Observe the manufacturer’s instructions.
Additionally for a Vitocell 100:
We recommend that the correct function of the sacrificial
anode is checked annually by your heating contractor.
The anode function can be checked without interrupting
the system operation.
The heating contractor will check the ground current with
an anode tester.
Safety valve (DHW tank)
The safety valve function should be checked every six
months by venting, either by the system user or the
local heating contractor. The valve seat may become
contaminated (see the valve manufacturer’s instructions).

Setback mode (reduced heating mode)
Heating curve
See “Reduced heating mode”.
Heating curves illustrate the relationship between the
outside temperature, room temperature (set value) and
boiler water or (heating circuit) supply temperature.
The lower the outside temperature, the higher the boiler
water temperature or heating circuit supply temperature.
With the heating program you determine whether you
heat your rooms and DHW, or only heat DHW, or whether
you shut down your heating system with frost protection
monitoring.
You can select the following heating programs:
H “Heating and DHW”
The rooms are heated and DHW is provided (winter
mode).
H “only DHW”
DHW is provided but there is no central heating
(summer mode).
H “Standby mode”
Frost protection for the boiler and the DHW tank is
enabled, no central heating, no DHW heating.
Note: No operating program is available for central
heating without DHW heating. When you want
central heating, hot water is generally also required
(winter mode. If you do want just central heating,
select the heating program “Heating and DHW”
and set the DHW temperature to 50° F (10° C)
(see chapter “Setting the DHW temperature”). This
means that you will not heat DHW unnecessarily,
but frost protection of the DHW tank is ensured.
In order to guarantee sufficient heat and minimum fuel
consumption at any outside temperature, the conditions
of your building and your heating system must be taken
into consideration. The heating curve is set by your
heating contractor for this purpose.
Note: If your heating system includes heating circuits with
mixing valves, then the supply temperature for the
heating circuit without mixing valve is higher by
a selected differential than the supply temperature
for the heating circuits with mixing valve.

Example:
For outside temperature 7° F (−14° C):
Legend
A Underfloor heating system, slope 0.2 to 0.8
B Low temperature heating system, slope 0.8 to 1.6
C Heating system with a boiler water temperature in
excess of 167° F (75° C), slope 1.6 to 2.0
Factory settings: Slope = 1.4 and shift = 0
Heating circuit
A heating circuit is a sealed circuit between the boiler and
radiators, in which the heating water circulates.
A heating system may comprise several heating circuits.
For example, one heating circuit for the rooms occupied
by you and one heating circuit for the rooms of a separate
apartment.
Heating circuit pump
Circulation pump for the circulation of the heating water
in the heating circuit.

Standard heating mode
When you are in the house during the day, you can heat
the rooms in standard heating mode. Set the periods
using the time program for central heating. During these
periods, the rooms are heated to the standard room
temperature.
5693 974 - 01
Outside temperature
A mixing valve mixes the water heated in the boiler
with the cooled water returning from the heating circuit.
The water, heated to the right temperature in line with
demand, is pumped to the heating circuit by the heating
circuit pump. The control unit adjusts the heating circuit
supply temperature via the mixing valve to the various
conditions, e.g. different outside temperature.

Standard room temperature
Summer mode
Set the standard room temperature when you are
at home during the day (see chapter “Setting the room
temperature”).
Heating program “Only DHW”.
At warmer times of the year, i.e. when rooms do not
have to be heated, you can disable heating mode.
The boiler remains operational for DHW heating.
Open flue operation
The combustion air is drawn from the room where the
boiler is installed.
DHW tank primary pump
Balanced flue operation
Drinking water filter
The combustion air is drawn from outside the building.
A device that removes solids from the water.
The drinking water filter is installed in the cold water pipe
upstream of the DHW tank or the instantaneous water
heater.
Reduced heating mode
When you are out or during the night, you can heat
the rooms in reduced heating mode (setback mode).
Set the periods using the time program for central heating.
During these periods, the rooms are heated to a reduced
room temperature.
Circulation pump for heating the DHW in the DHW tank.
Weather-compensated mode
When you are out or during the night, set the reduced
room temperature (see chapter “Setting the room
temperature”).
See also “Reduced heating mode”.
In weather-compensated mode, the heating supply
temperature is controlled according to the outside
temperature.
This means that no unnecessary heat is generated in
order to heat the rooms to the set room temperature you
selected.
The outside temperature is captured and transmitted
to the control unit by a sensor fitted outside the building.
Safety valve
DHW circulation pump
Reduced room temperature
A safety device that must be installed by your heating
contractor in the cold water pipe. The safety valve opens
automatically to prevent excess pressure in the
DHW tank.
The DHW circulation pump transports the hot water
around a circuit between the DHW tank and the drawoff points (e.g. hot tap). This makes hot water available
quickly at the draw-off point.
Solar circuit pump
In conjunction with solar thermal systems.
The solar circuit pump delivers the cooled heat transfer
medium from the DHW tank indirect coil to the collectors.
